Code Description

ICD-10 O15.03 is a billable code used to indicate a diagnosis of eclampsia complicating pregnancy, third trimester.

Key Diagnostic Point:

Eclampsia is a severe complication of pregnancy characterized by the onset of seizures in a woman with preeclampsia, typically occurring in the third trimester. It is a life-threatening condition that requires immediate medical intervention. The seizures can lead to significant maternal and fetal morbidity and mortality. Management of eclampsia involves stabilization of the patient, seizure control with medications such as magnesium sulfate, and often necessitates emergency delivery of the fetus, especially if the mother or fetus is in distress. Neurologic complications can arise, including cerebral edema, intracranial hemorrhage, and long-term neurological deficits. The condition is a critical indicator of severe preeclampsia and requires careful monitoring and management by obstetric healthcare providers to ensure the safety of both mother and child.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between eclampsia and other seizure disorders.
  • Understanding the severity of preeclampsia and its progression to eclampsia.
  • Emergency delivery protocols and their documentation.
  • Management of neurologic complications and their implications for coding.

Audit Risk Factors

  • Inadequate documentation of seizure activity and management.
  • Failure to document the timing and method of delivery.
  • Lack of clarity on the patient's pre-existing conditions.
  • Improper coding of associated neurologic complications.

Frequently Asked Questions

What is the difference between eclampsia and preeclampsia?

Preeclampsia is characterized by high blood pressure and protein in the urine during pregnancy, while eclampsia is a severe progression of preeclampsia that includes seizures. Accurate coding requires distinguishing between these two conditions based on clinical documentation.
